By analyzing TPSN synchronization protocol and various uncertain factors, this paper summarizes the concept of wireless sensor network and the research status of clock synchronization technology in wireless sensor network. To solve the problem that TPSN did not estimate the clock frequency drift, a new idea of wireless sensor network development is proposed: the node local clock self-correction method. The average clock deviation index is designed to evaluate the clock accuracy in a synchronous period. The experimental results show that this method is easy to implement. The synchronization period can be extended, the synchronization cost can be reduced and the energy consumption can be saved.
